Question

Which of the following is a solution to √x+10 +3=8?

x = 15

x = 5

x = –5

x = –15

Answer 1

\[\large \sqrt{x} + 10 + 3 = 8\]

like that?

Answer 2

no, x+10 is under the radical sign, +3=8 is not

Answer 3

Ahh that makes sense...

\[\large \sqrt{x + 10} + 3 = 8\]

isolate the radical...by subtracting 3 from both sides...

\[\large \sqrt{x + 10} = 5\]

Now square both sides of the equation to get rid of the radical...

\[\large x + 10 = 25 \]

And finally subtract 10 from both sides of the equation...

\[\large x = 15 \]

Answer 4

Hope that makes sense @skltngrl12 :)
